TCA 305 TCA 355
Proximity Switch
TCA 305 TCA 355
Bipolar IC
Features
q Lower open-loop current consumption; IS < 1 mA q Lower output saturation voltage q The temperature dependence of the switching
distance is lower and compensation of the resonant circuit TC (temperature coefficient) is easier
q The sensitivity is higher, so that larger switching
P-DSO-8-1
distances are possible and coils of a lower quality can be used
q The switching hysteresis remains constant as regards
temperature, supply voltage and switching distance
q The TCA 305 even functions without external
integrating capacitor. With an external capacitor (or with RC combination) good noise immunity can be achieved
q The outputs are temporarily short-circuit proof (approx.
10 s to 1 min depending on package)
q The outputs are disabled when VS < approx. 4.5 V and
P-DIP-14-1
are enabled when the oscillator stabilizes (from VS min = 5 V)
q Higher switching frequencies can be obtained q Miniature package

Pin Configurations (top view) The devices TCA 305 and TCA 355 contain all the functions necessary to design inductive proximity switches. By approaching a standard metal plate to the coil, the resonant circuit is damped and the outputs are switched. Operation Schematic: see TCA 205 The types TCA 305 and TCA 355 have been developed from the type TCA 205 and are outstanding for the following characteristics: Logic Functions Oscillator not damped damped Outputs Q H L L H
